IMPROVEMENT IN MILL-PICK HOLDERS.

Specification forming part of Letters Patent No. 118,753, datedSeptember 5, 1871.

To all whom it may concern Be it known that 1, JAMES P. SINCLAIR, ofMottville, in the county of Onondaga and State of New York, haveinvented a new and useful Improvement in Mill Iick Holder; and I dohereby declare that the followin g is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawingforming part of this specification, in which Figure 1 is a front view ofmy improved millpick holder. Fig. 2 is aside view of the same, partly insection, through the line a; r, Fig. 1, to show the construction.

Similar letters of reference indicate corresponding parts. v

My invention has for its object to furnish an improved holder formillacks, which shall be so constructed as to adjust itself snugly tothe pick, whatever may be its bevel, and which will hold the pick firmlyand steadily and will allow the pick to be conveniently detached whendesired; and it consists in the construction and combination of thevarious parts of the holder, as hereinafter more fully described.

A is the head of the holder, which is a short, hollow, flattenedcylindeigmade with solid ends. In the flattened sides of the head A,directly'opposite each other, are formed two slots, c a,

the slot c in the forward side being made considerably wider than theother or rear slot a B are two semicircular blocks, which are placed inthe semicircular cavities in the head A, one upon each side of the slotsa (t the larger slot ((1 being made of such a size that the said blocksB may be readily passed in and out through it. Upon one of the narrowsides of the head A is formed, or to it is rigidly and firmly attached,a socket, (J, to receive the handle D. E is the pick, which is insertedthrough the slots (0 a between the two blocks B, which adjust themselvesto the bevel of the upper part of the pick E, whatever that bevel maybe.

The flat sides or faces of the semicircular blocks B may be faced withleather or other suitable material, to enable them to fit more snugly tothe pick E.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The short, hollow, flattened, and slotted cylindricalhead A, provided with a socket, C,to receive a handle, D, and thesemicylindrical blocks B, whether faced or not, in combination with eachother, to adapt them to receive and hold a pick, E, substantially asherein shown and described.
